AUTOMOBILE-LAMP.

To all whom it may concern:

Be it known that. I, WILLIAM F. PERSONS, a citizen of the United States,residing at Lakewood, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Automobile- Lamps, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

This invention relates generally to automobile lamps and it has for itsobject to provide certain improvements to the auto-v mobile lamp now incommon use whereby the intense glare can be eliminated when desired anda sullicient amount of light-f thrown directly upon the road at theproper distance in advance of the automobile.

Another object of the invention is to provide the improvements in suchform, and arranged in such manner as will not interfere with the main orgeneral searchlight functions of the lamp when it is desired-troy employall of the light rays.

With these objects in view, the invention consists in the arrangement ofa supplemental reflector within the confines of the main reflector,preferably adjacent one edge thereof and at a slight 'angle to the axisof the main reflector so that by cutting out the main source of lightfrom the main reflector and cutting in the supplemental source of lightwithin the supplemental reflector a smaller light will be thrown uponAthe road the proper distance in advance of the auto-v54 mobile.

The invention consists also in certain de-` tails of construction andarrangement hereinafter fully described and 'pointed out in the claims.

In the drawings forming apart of this specification Figure 1 is alongitudinal sectional view` of an automobile lamp embodying myinvention; `Fig. 2 is a front view of the same; and Fig. 3 is adiagramigitic'- view illustrating the lines of reflection of*Y-` thelight rays from both the main and supplemental reflectors.

Inasmuch as my invention can be appliedA to any and all of the wellknown types of electric automobile lampsIfhave shown the same applied toone in which A indicates the outer shell or body ofthe lamp, and B thereflector arrangedtherein, this reflector being preferablywparabolic andhaving a Specification of Letters Patent.

central opening in which is arranged the socket for the incandescentlight C. This incandescent lamp may be adjustable or stationary aspreferred. The lamp is provided with lthe usual glazed front D 4whichmay be secured `in any suitable 'manner such as a clamping ring E.

' F' indicates a supplemental reflector which -in diameter is slightlyless than oneto the main reflector by means of screws or rivets I and itwillv be noted that the lower edge of the supplemental reflector is setslightly back from the lower edge of the main1 reflector while the upperedge K is on aline with the outer edge of the main reflector, It willalso bev noted that this upper edge K approximates the center of themain reflector and its source of light. Both the inner and the outersurface of the supplemental reflector H are polished to providereflecting surfaces.

When the lamp is use'd in the city, where the intense glare isobjectionable, and often prohibited, the supplemental source of. light1s employed, the main source being cut out and thevrays of light arereflected downwardlyupon the road directly in advance of. the car, andthe reflectors 'being small,

vof the` supp emental reflector can be secured only a sufficient amountof light will be, ro-

jeted to enable the driver to obtain a; c ear vision of the path oftravel. Whem how*- 'eventhe car is traveling in .the rural districts oropen country and it is desired to use the full power of the lamp thesupplemen V tal source of light is cut out andthe main source cut in,and inasmuch as the rear surface of the su plemental reflector ispolished to provi e a reflecting surface the lightrays which wouldotherwise vbe 0bvstrwtecl by said snpplementalreector are.

' most power is needed.

``While I have shown only one'formV of my 4`invention it is obvious thatcertain changes und modifications cnn be ,mede without departing fromthe broad principle thereof Within 'the scope and meuningofthe nppendedclaims.

Having thus describeddiny invention, whetI claim iis1- 'f l. In a lamp,the combination with a main unbroken reflector', of n supplementnlreflector arrengedwithin the confines of the mein reflector and adjacentthe edgethereof, Said supplemental reflector being of less diameterthenthe main reflector.

Q In a lmnp, the combination with a main unbroken reflector und itssource of light, of e supplemental reflector and its source ofrligbt.said supplemental reflector being 'i-renged Within the confines of themain reflector und et :in angle to the axis of saliti main reflector.

3. In e. lmnp, the combination with a main unbroken reflector und itssource of light, of e supplemental reflector und its source of light,said supplemental reflector being of considerably less diameter thanthemain relleotor,` arranged within the ,conlines thereof adjacent one edgeand at un :ingle to the axis of said mein reflector.

4. In :t lump. the combination with un unbroken reflector und its sourceof light, of n. supplemental reflector and in independent source oflight7 said supplemental reflector being of considerably less diameterthan the main reflect-o1' und arranged Within the confines thereof.

In a-lunip, the combination with an unbroken reflector and its sourceoflight,.of a supplemental. reflector and its source of light, saidsupplemental rellector being :Lrranged within the confines of the mainreflector adjacent onev edge thereof and .in

advance of the source of light Aofthe mein, reflector, both the innerand outer surfaces of said supplementnlyrellector being reflect-' y ingsurfaces.

In testimony whereof, I hereunto atlix my signature. y WILLIAM. F.PERSONS.
